It's a trap!
Last week I bought a bottle of Diet Pepsi from a vending machine. I opened it up, and woohoo! The cap was a winner - buy one 20 oz bottle, get one free.
I held onto the cap until Monday, when I was having a bad caffeine craving. So I redeemed it, and when I opened the second bottle, guess what? Another winner.
Fast-forward to today. I turned in that winner and got another two-fer. I opened the second bottle, and guess what? Yep, another winner.
I think it’s a trap.
